( Figs 1–12 )

Description. FEMALE ( Figs 1–6 ). Total body length of holotype 645 (605–640 in five paratypes). Gnathosoma . Infracapitulum sparsely punctated. Each transverse branch of peritremes with 1–2 chambers, each longitudinal branch with 6–7 chambers ( Fig. 4 ). Stylet of movable digit 90 (90) long. Stylophore sparsely punctated, 130 (130) long. Idiosoma . Propodonotal shield well sclerotized, punctated, bearing bases of setae vi, ve, si, and c1. Setae se situated near this shield and slightly posterior to level of setae c1. Length ratio of setae vi: ve: si 1:1.5–1.9:9.5–11. Hysteronotal shield narrow ( Fig. 1 ), fused to pygidial shield, weakly sclerotized, striated. Setae d2 situated about 1.3 times closer to d2 than to e. Length ratio of setae d2:d1:e 1:1– 1.5:1–1.8. Setae h1 and f1 subequal in length. Setae h2 1.5–1.7 times longer than f2. Aggenital setae ag1 and ag2 subequal in length, both slightly (1.1–1.2 times) shorter than ag3. Genital setae g1 and g2 subequal in length, both short. Pseudanal setae ps2 1.3–1.5 times longer than ps1. Genital plate weakly sclerotized, striae visible ( Fig. 5 ). Cuticular striations as in Figs 1 and 2 . Legs. Coxal fields of legs I–IV well sclerotized and punctated. Setae tc”III–IV 1.4–1.6 times longer than tc’III–IV. Fan-like setae p’ and p” of legs III and IV with 6 tines each ( Fig. 6 ). Setae 3c 3.6–3.8 times longer than 3b.

MALE ( Figs 7–12 ). Total body length 435–450 in two paratypes. Gnathosoma . Infracapitulum punctated. Each transverse branch of peritremes with 2 chambers, each longitudinal branch with 8 chambers ( Fig. 9 ). Stylet of movable digit 90 long. Stylophore sparsely punctated, 100–105 long. Idiosoma . Propodonotal shield weakly sclerotized, margins indistinct, punctated, bearing bases of setae vi, ve, si and c1. Setae se situated near this shield and anterior to level of setae c1. Hysteronotal shield with indiscernible margins, striae visible, punctated. Setae d2 situated equidistant to d2 and e. Setae vi, ve, si, d1, d2, e and f short and subequal in length. Setae h 2.5 times longer than f. Setae ag1 about twice longer than ag2. Pygidial shield small, restricted to ano-genital region ( Fig. 9 ). Cuticular striations as in Figs 11 and 12 . Legs. Coxal fields of legs I–IV punctated. Fan-like setae p’ and p” of legs III and IV with 5–6 tines each ( Fig. 10 ).
